eteCh nitrogen generators

regeneration

ETech membrane modules contain thousands of hair-like membranes that collectively separate large amounts of high purity, dry nitrogen directly from compressed air, which may be applied to prevent degradation of cargo sensitive to oxygen, moisture or combustion by-products. The dry gas from these systems are also ldeal as non-freezing, non-corrosive instrument gas, and for drying of cofferdams.

For years it has been a well-known problem that membranes may often be exposed to contamination, and as a consequence will become deficient in terms of performance. Air-gas separation membranes are sensitive to contaminations from hydrocarbon aerosols/liquid (i.e. oil products) in the sense that such contamination cannot be removed nor can the membrane be regenerated, without running the risk of destroying the membrane. Most membrane based nitrogen generators have traditionally been equipped with oil lubricated feed air compressors, which increases the risk of oil contamination of the membranes. Traditionally, this problem has been dealt with by applying traditional filtration techniques upstream the membrane. These techniques, combined with increasing the feed air temperature after filtration, results in a gap between the actual temperature of oil and water vapor versus dew point temperature of these, thus avoiding condensation of vapor. Even though filtration

equipment is installed, there will always be a risk of oil vapor carryover into the membrane. One of the situations that may contribute to this risk is that the traditional air-gas separation membrane normally has a recommended max. operating temperature of 50 °C. The compressor cooling water available may have a temperature of 36 °C, which, owing to the feed air temperature rise across the compressor, may result in a feed air temperature of as much as 46 °C, prior to the temperature increase required to avoid vapor condensation.

This leaves us with a temperature gap of only 6 °C, which is not enough to avoid vapor condensation, because there is a temperature drop higher that this across the membrane, during the separation process. With the new ETech membranes, these problems are avoided, because, at first, the membrane material, polyamide, consists of a single composition, and not, as many other membranes, a dual

composition, where the governing membrane is a thin layer applied on to a substructure. The two layers are normally of different materials. The polyamide may withstand a much higher temperature (typically as much as 130 °C), and may easily operate at a temperature of 60 °C, thus avoiding the risk of vapor condensation owing to lower operating temperatures. If however, there should be a vapor carryover, due to filtration failure or excess oil carryover from compressor, then the ETech membranes may be regenerated. WME can therefore offer an exchange arrangement, provided that ETech membranes are already installed. It is quite apparent, the cost savings in such an arrangement, as opposed to purchasing brand new membranes. The Life Cycle Cost of Nitrogen generators can be reduced with as much as 60% compared to a normal membrane set up, and will also contribute to increased safety, in terms of regularity and system capacity.

advantages:• Low cost with on-site generation, saves up to 50%• Wide capacity range• Dry nitrogen, dewpoint @ atm. pressure 70°C• Purity 95-99,9%• Easy to install, operate and maintain.

marine nitrogensystems

eng mThe ENG M systems (designed for Chemical tankers) and ENG systems (designed for Offshore supply vessels) consist of free standing feed air compressors and fully automated Nitrogen generation units. The latest PLC systems are applied for control of product qualities and for signal output to ship integrated control systems. Product purity is automatically monitored and controlled. If the product purity is not maintained, the generated nitrogen will be vented automatically.

WME Marine Nitrogen systems are based on modular design principles. Membrane modules can be added or replaced in order to upgrade the system in rated capacity after initial installation. This design principle allows for system expendability, in most cases without the need of replacing the existing system. Furthermore light weight and compact design of the membranes allow us to transport and install the Nitrogen systems easily to a wide range of process application and in various locations and conditions.

oFFshore nitrogen systems

eteCh membraneThe ETech membrane systems has a high capacity to weight relationship compared with other non-cryogenic sources. Etech membrane systems are relatively lightweight and compact, enabling them to fit into places where space is limited. The systems are portable, stand alone units that require only supply of dry, compressed air. These computerized, automated process control systems are an ideal choice for applications requiring purities up to 99,9%, as well as extremely precise control capability, data logging, or remote operation and communication. These systems can be applied within a wide capacity range.Membrane produced nitrogen can be supplied over a wide range of purities. Modular system design allows for system expansion with the addition of modules, increasing nitrogen capacity as your requirements change. System layouts can be configurated to meet the most unique site requirements.

LngThe nitrogen generating plant can serve various purposes such as supply of nitrogen gas into the insulation void spaces, for purging of fuel gas line in engine room, for purging of cargo liquid line, vapor line, gas line, vent masts and related cargo equipment as well as for sealing of the penetration shaft and shaft seal of high duty and low duty compressors. The insulation void spaces normally is to be pressurized/maintained by nitrogen vapor from the nitrogen generator and vented to the atmosphere through vent control valves.
